FIG. 3 is a flowchart illustrating an exemplary process for counting andregulating pedestrian volume in a public place of a smart city accordingto some embodiments of the present disclosure. As shown in FIG. 3 , insome embodiments, the process 300 may be performed by a processingdevice.

In 310, a query request for an intended place initiated by a user may bereceived based on a user platform.

The intended place may be a place that a user intends to go to. Forexample, the intended place may be places, such as a shopping mall, arestaurant, a school, an administrative center, an office building, orthe like. In some embodiments, the intended may be a place input by theuser on a user terminal, for example, the user may input a specificrestaurant name, etc. on the mobile phone.

A query request may be content that the user searches for relevantinformation of the intended place. For example, the query request mayinclude query content such as a location, a function, whether iscontrolled or not, information of pedestrian volume, etc. of theintended place. In some embodiments, if the query request is obtained byinput of the user on the user terminal, the user terminal may be used asa user platform to obtain the query request.

In 320, the query request may be transmitted, based on a serviceplatform, to a management platform, a query instruction may be generatedbased on the management platform, and the query instruction may includea regional location of the intended place.

The query instruction may be information extracted from the queryrequest that may be identified by a system. For example, the queryinstruction may include information such as a regional location, a querytime, a query method, etc. of the intended place.

The regional location may be information that reflects a geographicallocation of the intended place. For example, the regional location maybe a latitude and a longitude, a coordinate, a relative distance from acurrent location of the user, etc.

In some embodiments, the query request received from the user platformmay be sent to the management platform for preliminary processingthrough the service platform to form a query instruction that may beidentified by the system. For example, the query instruction may be amatrix, a data table, etc. composed of information such as the regionallocation, the query time, the query method, etc. of the intended place.

In 330, the query instruction may be issued, based on the managementplatform, to a sensor network sub-platform of the sensor networkplatform corresponding to the management platform according to theregional location.

In some embodiments, the sensor network platform may include a pluralityof sensor network sub-platforms, and different sensor networksub-platforms may be configured to receive query instructions ofdifferent regional locations issued by the management platform. Thesensor network platform may perform data storage, data processing,and/or data transmission for data of different object platforms by usingthe sub-platforms of different sensor network platforms. Differentsensor network sub-platforms may correspond to different regionallocations.

In 340, the query instruction may be sent, based on the sensor networksub-platform, to the object platform corresponding to the sensor networksub-platform.

In some embodiments, the object platform may include a plurality ofobject sub-platforms, and different object sub-platforms may correspondto different regional locations. For example, if different objectsub-platforms are set in different regional locations, the sensornetwork sub-platform and the object sub-platform corresponding to a sameregional position may have a corresponding relationship. The sensornetwork sub-platform may send the query instruction to an objectsub-platform corresponding the sensor network sub-platform.

In 350, a query result may be obtained based on the object platformaccording to the query instruction, and the query result may includecurrent information of the intended place and recommendation informationof a relevant place.

The query result may be information related to the intended place. Forexample, the query result may include current information of theintended place and recommendation information of a relevant place.

The current information may be real-time information of the intendedplace. For example, the current information may include information onreal-time pedestrian volume of the intended place, information onwhether the intended place is currently under control (accessrestriction), information on restrictions on roads around the intendedplace, or the like.

The relevant place may be a place with similar features to the intendedplace. For example, the relevant place may be a place with similarfunctions. If the intended place is a shopping mall, the relevant placemay be a pedestrian street, a supermarket, etc. If the intended place isa hospital, the relevant place may be an outpatient department, apharmacy, or the like. As another example, the relevant place may be aplace where there is a similar regional location. If the intended placeis a certain parking lot, the relevant place may be other parking lotsnearby. In some embodiments, a spatial distance between the relevantplace and the intended place may be within a preset range.

The recommendation information may be information that the relevantplace is recommended to the user. For example, the recommendationinformation may be information in forms such as text, voice, an image,or the like, or any combination thereof.

In some embodiments, the query result may be further determined in wayssuch as based on a sensor, manual input, a preset rule, or the like. Forexample, the object platform may obtain information on real-timepedestrian volume as the query result through a pedestrian volumemonitoring sensor. As another example, the object platform may useresponse of an artificial customer service to the query request as thequery result. As yet another example, the object platform may determinethe query result by comparing regional locations of each place and theintended place, and the object platform may determine the query resultby classifying the places based on function, or the like. For example,by comparing a coordinate, a longitude and a latitude, etc., therelevant place of the intended place may be determined, or the relevantplace related to the function of the intended place may be determinedthrough a preset place function classification table.

In 360, the query result may be fed back, based on the object platform,to the user platform through the sensor network sub-platform, themanagement platform, and the service platform corresponding to theobject platform respectively.

The process of feeding back the query result from the object platform tothe user platform is an inverse process of the above transmissionprocess of the user request and the query instruction, which will not berepeated herein.

In some embodiments, the process 300 may also include an operation 370that the object platform determines, based on the query request for theintended place and the current information of the intended place, amanagement and control strategy for the intended place.

The number of the operation 370 is merely for convenience ofdescription, and does not mean that the sequence of the operations islimited. For example, the operation 370 may be performed between theoperation 350 and the operation 360. In some embodiments, the operation370 in the process 300 may be optional, that is, the operation 370 maynot be included.

The management and control strategy may be a plan to limit thepedestrian volume, limit the movement, and limit the access for theintended place. For example, the management and control strategy mayinclude information such as a control time range, a control space range,a control operator arrangement, a pedestrian volume diversion planning,etc.

In some embodiments, the management and control strategy may bedetermined based on a preset of system. For example, when the currentpedestrian volume of the intended place exceeds a threshold ofpedestrian volume preset by the system, the management and controlstrategy may be determined to be measures such as limiting thepedestrian volume and diverting the pedestrian volume. The objectplatform may obtain the management and control strategy generated by thesystem based on a sensor network sub-platform corresponding to theobject platform.

In some embodiments, the management and control strategy may bedetermined based on a user setting. For example, the user may makespecific settings for the management and control strategies such as aroad construction, an epidemic, etc. based on situations of emergencies.The object platform may obtain the management and control strategymanually input based on the sensing network sub-platform correspondingto the object platform. Further descriptions regarding the determiningthe management and control strategy of the intended place may be foundin FIG. 7 and relevant descriptions.

Through the method for counting and regulating pedestrian volume in apublic place described in some embodiments of the present disclosure, arelevant place and a management and control strategy recommended to theuser can be realized based on a situation of current pedestrian volumein a certain place. Through the intelligent recommendation based onpedestrian volume, on the premise of preventing the user from going to aplace with high pedestrian volume, the request of the user may be met asmuch as possible, which can improve the user experience.

It should be noted that the descriptions of the above process 300 ismerely provided for the purposes of illustration, and not intended tolimit the scope of the present disclosure. For those skilled in the art,multiple variations and modifications may be made to the process 300under the teachings of the present disclosure. However, those variationsand modifications do not depart from the scope of the presentdisclosure. For example, the process 300 may also include apreprocessing operation.

FIG. 4 is a schematic diagram illustrating an exemplary process fordetermining a relevant place according to some embodiments of thepresent disclosure.

As shown in FIG. 4 , a relevant place in a query result may bedetermined through the following process 400. Based on an objectplatform, information of the intended place and the relevant place in aregional place map 420 may be obtained according to a query request 410,and a query result 430 may be generated.

In some embodiments, the query request may include an intended place.The object platform may extract information related to the intendedplace in the query request, and find a node corresponding to theintended place in the regional place map. For example, the query requestof the user may include information such as a name, a positioncoordinate, a function type, etc. of the intended place. Based on theabove information, the object platform may find the node correspondingto the intended place related to the above information in the regionalplace map.

In some embodiments, the object platform may determine a nodecorresponding to the relevant place based on the node corresponding tothe intended place. In some embodiments, the object platform maydetermine the node corresponding to the relevant place based onattributes of the node corresponding to the intended place. For example,the node corresponding to the relevant place may be determined based ona place location, a place type, etc. of the node corresponding to theintended place. In some embodiments, the relevant place (thecorresponding node) may be determined through the operations of S1 toS3.

In some embodiments, the object platform may generate the query result.For example, the object platform may input the attributes of the nodescorresponding to the intended place and the relevant place into a presettable of query results as the query result.

The regional place map 420 may represent mutual relationship among allplaces and features of each place included in a certain region. Aregional size may be set according to the query request of the user, forexample, a region may be a city, a district/county, a township, etc. Theplace in the regional map may be represented based on the node in theregional place map. The features of the place may be obtained based onthe attributes of the node. The mutual relationship between the placesmay be obtained based on edges in the regional place map. In someembodiments, the regional place map may be further obtained by importingexisting map data as basic data and based on manual marking, or thelike.

The regional place map may include a plurality of nodes, and differentnodes in the regional place map may represent different places. Forexample, node 1 may represent a certain parking lot in the regionalplace map, node 2 may represent a certain hotel in the regional placemap.

In some embodiments, each node may include the attributes of the node.The attributes of the node may be parameters of the node. For example,the attributes of the node may include place real-time information,place basic information, etc. of the place corresponding to the node.

The place real-time information may be information that dynamicallychanges according to a real-time situation of the place. For example,the place real-time information may include current pedestrian volume,current management and control information, or any combination thereof.

The current pedestrian volume may be passenger flow volume in the placeat a current time or within a certain time period close to the currenttime. In some embodiments, the current pedestrian volume may be detectedby a sensor installed in a place or a relevant road section.

The current management and control information may be managementinformation of the pedestrian volume in the place at a current time orwithin a certain time period close to the current time. For example, thecurrent management and control information may include information suchas limiting, diverting, complete opening, etc. of pedestrian volume. Insome embodiments, the current management and control information may beinput by a user or obtained through a network.

The place basic information may be relatively fixed information thatdoes not change over time. For example, the place basic information mayinclude a place type (that is, a place function), a place location (suchas a coordinate or a latitude and a longitude), or any combinationthereof.

The place type may be a function type of the place. For example, theplace type may include a type such as catering, shopping, school,accommodation, medical care, etc. The place location may be ageographical location to which the place specifically relates. Forexample, the place location may be information, such as a latitude, alongitude, a coordinate, etc. where the place is located.

An edge 424 in the regional place map may be configured to connect twonodes, a mutual relationship of which meets a preset condition.Attributes of the edge may represent a relationship between differentnodes in the regional place map. The attributes of the edge may includean edge weight. The edge weight may reflect a correlation between twonodes to be connected or connected. For example, the edge weight may be1, 2, 10, etc. The larger the edge weight is, the weaker the correlationbetween the two nodes is.

In some embodiments, the preset condition that needs to be met betweenthe two connected nodes may be related to the edge weight between thetwo nodes. For example, the preset condition may be that the edge weightis lower than or equal to a preset threshold, or the like.

In some embodiments, the edge weight may be determined by a place typedifference and a spatial distance of places corresponding to twoconnected nodes.

The place type difference may be a type difference of placescorresponding to two nodes. In some embodiments, the place typedifference may be represented by a place type difference value within arange of 0 to 5. The larger the place type difference value is, thegreater the function type between two places is. For example, the placetype difference value between different shopping malls may be 0. Theplace type difference value of a shopping mall and a retail departmentmay be 1. The place type difference value of a shopping mall and aparking lot may be 5, or the like.

The spatial distance may be a straight line distance between places. Insome embodiments, the spatial distance may be represented by a spatialscore within a range of 0 to 5. The larger the spatial score is, thecloser a distance between two places is. For example, for two placeswith a spatial distance ranging from 0 to 200 meters, the spatial scoremay be 5. For two places with a spatial distance of more than 2000meters, the spatial score may be 1.

In some embodiments, an edge weight of an edge between two nodes may becalculated through a place type difference value and a spatial score.For example, an edge weight of two nodes A and B may be calculatedthrough the following equation (1):

Q _(AB)=10−(X _(AB) −D _(AB))  (1),

where Q_(AB) denotes an edge weight between the two nodes A and B,X_(AB) denotes a spatial score between the node A and the node B, andD_(AB) denotes a place type difference value between the node A and thenode B.

In some embodiments, the spatial score and the place type differencevalue may be weighted for calculation, that is, the edge weight of anedge between two nodes may be weighted calculation values of the spatialscore and the place type difference value of the two nodes. For example,the edge weight of the edge between the two nodes A and B may becalculated through the following equation (2):

Q _(AB)=10−(m ₁ X _(AB) −m ₂ D _(AB))  (2),

where m₁ denotes a weight of the spatial score, m₂ denotes a weight ofthe place type difference value, and m₁+m₂=1.

In some embodiments, the weight of the spatial score and the weight ofthe place type difference value may be determined by manual setting, forexample, which are determined by a query request of a user.

In some embodiments, the preset condition that is met between twoconnected nodes may be that a place type difference of placescorresponding to the two connected nodes is smaller than a presetdifference value, or a spatial distance of places corresponding to thetwo connected nodes is less than a distance threshold.

Merely by way of example, the preset conditions may be that a place typedifference value of the places corresponding to the two connected nodesis less than 2, or the spatial distance of places corresponding to thetwo connected nodes is less than 200 m, or the spatial score is greaterthan 4.

In some embodiments, the relevant place may be determined through thefollowing process. Candidate places may be determined based on degree ofassociation and an edge weight. The relevant place may be determined,based on a query request, from the candidate places.

The degree of association may be degree of similarity and correlationbetween nodes. For example, the degree of association may be degree ofcorrelation between node locations (i.e., place locations) and nodetypes (i.e., place types). In some embodiments, the degree ofassociation may be divided into different levels. For example, thedegree of association may include different levels such as a primaryassociation, a secondary association, etc. The primary association maybe a level of the degree of association with a highest degree ofsimilarity and correlation between nodes. The secondary correlation maybe a level of the degree of association with a relatively high degree ofsimilarity and correlation between nodes. For example, as shown in FIG.4 , the node A and the node B are connected by only one edge, and thetwo nodes may be a primary association. The node A and the node D areconnected by at least two edges, and the two nodes may be a secondaryassociation, or the like.

The candidate place may be a place with the degree of association andthe edge weight meet a preset condition. For example, the presetcondition may be that the degree of association between the candidateplace and the intended place is a primary association or a secondaryassociation, and the edge weight corresponding to the edge between thecandidate place and the intended place is less than or equal to 4.

In some embodiments, the relevant place (i.e., the corresponding node)may also be determined through the following operations.

In S1, the regional place map may be divided, based on a presetalgorithm, into several sub-maps.

The preset algorithm may be the algorithm for dividing the regionalplace map according to certain rules. Based on the preset algorithm,each node in the regional place map may be clustered and divided basedon certain features. Detailed descriptions regarding the presetalgorithm may be found in FIG. 5 and relevant descriptions thereof.

The sub-map may be a sub-map formed by nodes with similar features andedges between the nodes in the regional place map. For example, thesub-map may be a set of a certain part of nodes and edges in theregional place map. The sub-map may include at least one node. Forexample, based on the preset algorithm, the regional place map 420 inFIG. 4 may be divided into two sub-maps, for example, such as a sub-map421 and a sub-map 425.

In S2, the target sub-map may be determined, based on the query request,from the several sub-maps.

The target sub-map may be a sub-map that contains an intended place. Insome embodiments, the target sub-map may include a target node (i.e., anintended place). In some embodiments, the object platform may designatethe sub-map where the intended place is located as the target sub-map.For example, if the target node in FIG. 4 is a node 422, the sub-map 421may be determined as the target sub-map.

In S3, a recommendation node may be determined based on the targetsub-map, and a place corresponding to the recommendation node may bedetermined as the relevant place.

A recommended node 423 may be a node that meets a preset requirement,for example, a node that is similar to the target node 422. In someembodiments, one or more nodes in a same sub-map as the target node(such as a node in the target sub-map 421 in FIG. 4 ) may be used asrecommendation nodes.

Through the regional place map described in the some embodiments of thepresent disclosure, the visual processing of the place function and theplace location can be realized, which is convenient for the judgment ofthe relevant place. In addition, the candidate place may be determinedby the degree of association and the edge weight between the nodescorresponding to the place, which improves the accuracy of the judgmentprocess.

FIG. 5 is a schematic diagram illustrating a preset algorithm accordingto some embodiments of the present disclosure. In some embodiments, theprocess 500 may be performed by an object platform.

In 510, one of n nodes included in the regional place map may bedesignated as a benchmark node to determine a shortest path from thebenchmark node to other nodes.

The benchmark node may be any node of all the nodes included in theregional place map. In some embodiments, in a division of the regionalplace map, each node (n) in the regional place map may be calculated asa benchmark node, respectively.

The shortest path may be a shortest edge connecting the benchmark nodeto other nodes through edges. For example, in FIG. 4 , when a node A isthe benchmark node, a shortest path from A to B may be an edge AB. Ashortest path from A to C may be an edge AC. A shortest path from A to Dmay be an edge ABD (i.e., an edge AB+an edge BD) or an edge ACD (i.e.,an edge AC+an edge CD). A shortest path from A to E may be an edge ABDEor an edge ACDE. A shortest path from A to F may be an edge ABDEF or anedge ACDEF. A shortest path from A to G may be an edge ABDEG or an edgeACDEG. A shortest path from A to H may be an edge ABDEH or an edgeACDEH. A shortest path from A to J may be an edge ABDEFJ, an edgeACDEFJ, an edge ABDEGJ, an edge ACDEGJ, an edge ABDEHJ, or an edgeACDEHJ. For a shortest path when another node is used as the benchmarknode, please refer to the shortest path when the node A is the benchmarknode.

In 520, based on the shortest path, an edge betweenness centrality valueof all edges in the regional place map may be calculated.

The edge betweenness centrality value (EBC value) may be a parameterrepresenting a proportion of a count of shortest paths passing through acertain edge in the shortest paths from the benchmark node to othernodes with a certain node as a benchmark node in the regional place map.

For example, when the node A is the benchmark node, the edge betweennesscentrality value of the edge AB may be: in shortest paths from the nodeA to other nodes (X), a sum of a proportion of paths passing through theedge AB in all paths from node A to other nodes X. For example, from thenode A to the node J, there are six paths of ABDEFJ, ACDEFJ, ABDEGJ,ACDEGJ, ABDEHJ, and ACDEHJ. The three paths of ABDEFJ, ABDEGJ, andABDEHJ pass the edge AB, so a value of 3/6 may be obtained. From thenode A to the node F, there are two paths of ABDEF and ACDEF. The pathABDEF passes through the edge AB, so a value of 1/2 may be obtained. Inthe same way, from the node A to be node H, a value of 1/2 may beobtained. From the node A to the node G, a value of 1/2 may be obtained.From the node A to the node E, there are two paths of ABDE and ACDE. Thepath ABDE passes through the edge AB, so a value of 1/2 may be obtained.From the node A to the node D, there are two paths of ABD and ACD. Thepath ABD passes through the edge AB, so a value of 1/2 may be obtained.From the node A to the node B, there is only one path of AB, so a valueof 1 may be obtained. From the node A to the node C, there is only onepath of AC without passing through the edge AB, so a value of 0 may beobtained. Therefore, the edge betweenness centrality value of the edgeAB may be 1/2+1/2+1/2+1/2+1/2+1/2+1+0=4.

Taking A as the benchmark node, a calculation method of edge betweennesscentrality values of other edges may refer to the calculation method ofthe edge AB. An edge betweenness centrality value of an edge AC may be4. An edge betweenness centrality value of an edge BD may be 3. An edgebetweenness centrality value of an edge CD may be 3. An edge betweennesscentrality value of an edge DE may be 5. An edge betweenness centralityvalue of an edge EF may be 4/3. An edge betweenness centrality value ofan edge EH may be 4/3. An edge betweenness centrality value of an edgeEG may be 4/3. An edge betweenness centrality value of an edge FJ may be1/3. An edge betweenness centrality value of an edge HG may be 1/3. Anedge betweenness centrality value of an edge GJ may be 1/3. An edgebetweenness centrality value of an edge BC may be 0. An edge betweennesscentrality value of an edge FH may be 0.

In 530, each node in the regional place map may be designated as abenchmark node in turn, the edge betweenness centrality value of eachedge in the regional place map may be calculated by repeating the aboveoperations when each node is designated as a benchmark node.

For example, when the node H is used as the benchmark node, shortestpaths from the node H to other nodes may be obtained: HF, HE, HJ, HED,HEG, HJG, HEDB, HEDC, HEDBA, and HEDCA. Edge betweenness centralityvalues of each edge may be obtained. An edge betweenness centralityvalue of an edge FH may be 1. An edge betweenness centrality value of anedge EH may be 11/2. An edge betweenness centrality value of an edge HJmay be 3/2. An edge betweenness centrality value of an edge DE may be 4.An edge betweenness centrality value of an edge EG may be 1/2. An edgebetweenness centrality value of an edge GJ may be 1/2. An edgebetweenness centrality value of an edge BD may be 3/2. An edgebetweenness centrality value of an edge CD may be 3/2. An edgebetweenness centrality value of an edge AB may be 1/2. An edgebetweenness centrality value of an edge AC may be 1/2. An edgebetweenness centrality value of an edge BC may be 0. An edge betweennesscentrality value of an edge EF may be 0. An edge betweenness centralityvalue of an edge FJ may be 0.

For calculation when other nodes are used as benchmark nodes, pleaserefer to the above calculation descriptions.

In 540, n edge betweenness centrality values of each edge in theregional place map obtained based on the operations may be obtained.

For example, after the edge betweenness centrality value is calculatedfor each edge by sequentially taking the node A to the node J in FIG. 4as benchmark nodes, 9 edge betweenness centrality values may be obtainedfor each edge.

In some embodiments, as shown in FIG. 6 , results obtained from theabove calculation may be made into a Table 600 to obtain the edgebetweenness centrality value corresponding to each edge when each nodeas the benchmark node.

In 550, a total value of edge betweenness centrality of each edge may beobtained by summing the n edge betweenness centrality values of eachedge.

The total value of edge betweenness centrality may be a sum of the edgebetweenness centrality values.

In some embodiments, the total value of edge betweenness centrality maybe obtained by directly adding each edge betweenness centrality value.For example, as shown in FIG. 6 , the total value of the edgebetweenness centrality of the edge AB may be a sum of 9 edge betweennesscentrality values of the edge AB. In the same way, the total value ofedge betweenness centrality of each other edge may be calculatedrespectively.

In some embodiments, the total value of edge betweenness centrality maybe obtained by weighed sum of each edge betweenness centrality value.

In some embodiments, the object platform may determine a second weightof each edge betweenness centrality value among n edge betweennesscentrality values of each edge in combination with a user requirement.Based on the second weight, a weighted sum value of the n edgebetweenness centrality values of an edge may be taken as a total valueof edge betweenness centrality of the edge.

The second weight may be contribution degree (importance degree) of eachedge betweenness centrality value to the total value of edge betweennesscentrality. In some embodiments, the second weight may be determined bya user request. For example, when the user request includes a higherdegree of attention to real-time pedestrian volume information, thedifference in pedestrian volume between two nodes corresponding to eachedge may be used as a weight of the edge. The larger the difference is,the smaller the weight corresponding to the edge is.

Applying weights to each edge betweenness centrality value based on theuser request may amplify the impact of the user request on the resultwhen the total value of edge betweenness centrality is calculated, sothat subsequent division of the regional place map may be more in linewith user experience.

In 560, a score value of edge betweenness centrality of each edge may beobtained based on the total value of the edge betweenness centrality ofeach edge.

The score value of edge betweenness centrality may be a parameterobtained by evaluating the total value of edge betweenness centrality.In some embodiments, the score value of edge betweenness centrality maybe a product of the total value of edge betweenness centrality and ascore coefficient. The score coefficient may be set by a user or take adefault value. For example, the score coefficient may be 0.5. As shownin FIG. 6 , if the total value of edge betweenness centrality of an edgeAB is 8, the score value of edge betweenness centrality of the edge ABmay be 4.

In some embodiments, the recommendation information of the relevantplace in the operation 350 may also include a recommendation index. Therecommendation index may be determined by processing the currentpedestrian volume information of each node and the relationship betweeneach node and the intended place in the target sub-map through arecommendation model to determine the recommendation index.

The recommendation model may be a model that determines a recommendationindex. The recommendation model may be a machine learning model. Forexample, the recommendation model may be a convolutional neural networkmodel.

An input of the recommendation model may include the current pedestrianvolume information of each node and the relationship between each nodeand the intended place. An output of the recommendation model mayinclude a recommendation index of each node.

The relationship between each node and the intended place may be anydata related to the intended place. For example, the relationshipbetween each mode and the intended place may be an edge weight of eachedge connecting the corresponding node and the node corresponding to theintended place in the target sub-map, a score value of edge betweennesscentrality of each edge connecting the corresponding node and the nodecorresponding to the intended place in the target sub-map, or the like.

The recommendation index may be a parameter that reflects the degree towhich the system recommends a certain relevant node. For example, therecommendation index may be a specific value such as 6, 9, etc., or therecommendation index may also be a recommendation level such asrelatively recommended, strongly recommended, not recommended, or thelike. In some embodiments, the recommendation index may be an integerwithin 0 to 10.

In some embodiments, the recommendation model may be trained andobtained based on a large number of training samples with labels. Insome embodiments, the training sample may be the historical pedestrianvolume information of each node and the relationship between each nodeand the intended place. The labels may be recommendation indexescorresponding to each node. The labels may be obtained by manualannotation.

The recommendation index may be determined by the recommendation model,which can quantify the recommendation degree of the node, reduce theunnecessary cost caused by manual recommendation, and improve therecommendation accuracy.

In 570, the regional place map may be divided based on the score valueof edge betweenness centrality score of each edge.

In some embodiments, the division process may be performed based on thescore value of edge betweenness centrality. For example, an edge with ahighest score value of edge betweenness centrality may be used as asegmenting edge, and the regional place map including the two nodescorresponding to the edge may be divided into two sub-maps. For example,based on the aforementioned calculation, score values of the edgebetweenness centrality of each edge in FIG. 4 may be as follows. A scorevalue of edge betweenness centrality of an edge FH may be 1. A scorevalue of edge betweenness centrality of an edge EH may be 34/6. A scorevalue of edge betweenness centrality of an edge HJ may be 19/6. A scorevalue of edge betweenness centrality of an edge DE may be 20. A scorevalue of edge betweenness centrality of an edge EG may be 14/3. A scorevalue of edge betweenness centrality of an edge GJ may be 11/3. A scorevalue of edge betweenness centrality of an edge BD may be 9. A scorevalue of edge betweenness centrality of an edge CD may be 9. A scorevalue of edge betweenness centrality of an edge AB may be 4. A scorevalue of edge betweenness centrality of an edge AC may be 4. A scorevalue of edge betweenness centrality of an edge BC may be 1. A scorevalue of edge betweenness centrality of an edge EF may be 34/6. A scorevalue of edge betweenness centrality of an edge FJ may be 19/6. In theregional place map 420, the score value of the betweenness centralityscore of the edge DE is the largest, that is, the edge DE may be used asa segmentation edge to divide the regional place map 420, and a sub-map421 and a sub-map 425 may be obtained.

In some embodiments, an edge whose score value of edge betweennesscentrality exceeds a threshold of score value may be used as asegmentation edge to divide the regional place map including the twonodes corresponding to each edge may be divided respectively to obtain aplurality sub-maps. The threshold of score value may be determined basedon a user setting.

In some embodiments, the target sub-map may be further divided accordingto the foregoing method based on the division result of the operationsto obtain a better division result, and based on the final divisionresult, places corresponding to other nodes in a same sub-map as thetarget node may be designated as recommended places.

In some embodiments, the aforementioned division operations may becontinuously repeated until each sub-map includes only one node. If onedivision corresponds to one stage, and after an original map is dividedy times, each sub-map includes only one node, then the entire divisionprocess may have y stages, and the modularity (represented by a letter Qin the equation) value corresponding to each stage may be calculated.The division result corresponding to the stage with a largest modularityvalue (Q value) may be taken as the optimal division result, and thesub-map obtained corresponding to the division result, and other nodeslocated in the same sub-map as the target node may be designated asrecommended places.

The modularity value may be understood as a difference between a networkand a random network under a certain clustering division. Because therandom network may not have a sub-map structure, the larger thedifference corresponding to a certain clustering division is, the betterthe sub-map division result is. The modularity value (Q value) may beobtained based on the following equation (3):

$\begin{matrix}{{Q = {\frac{1}{2m}{{\Sigma}_{vw}\left\lbrack {A_{vw} - \frac{k_{v}k_{w}}{2m}} \right\rbrack}{\delta\left( {c_{v},c_{w}} \right)}}},} & (3)\end{matrix}$

where m denotes a count of edges in the original map, v and w denote anytwo nodes in the map, A_(vw) denotes whether there is an edge betweenthe two nodes (if there is an edge, the value is 1, otherwise the valueis 0), k_(v) and k_(w) denote degrees of the node V and the node W,(c_(v), c_(w)) denotes whether the two node are in a same sub-map (ifthe two nodes are in the same sub-map, the value is 1, otherwise thevalue is 0). In some embodiments, a theoretical size range of the Qvalue is [−0.5, 1).

Through the preset algorithm described in the some embodiments of thepresent disclosure, a sub-map with a higher degree of association may beobtained. When a user initiates a query request, the result may bedirectly queried in a sub-map with a higher degree of association, whichavoids the huge amount of calculation caused by querying the entireregional place map and improves the query efficiency.

FIG. 7 is a schematic diagram illustrating an exemplary process fordetermining a management and control strategy of an intended placeaccording to some embodiments of the present disclosure. In someembodiments, the process 700 may be performed by an object platform.

In some embodiments, the object platform may determine a flow managementand control strategy of the intended place 730 based on a currentpedestrian volume of the intended place 710 and a count of usersquerying the intended place 720.

The count of users querying the intended place 720 may be a count ofusers who issue a query request within a certain time period. In someembodiments, the count of users who query within a certain time periodmay be less than or equal to a count of query requests. For example, asame user may issue a plurality of query requests within the timeperiod. By determining the count of users who query, the count of usersmay be used as a basis for a current or future pedestrian volume of theintended place.

The flow management and control strategy may be a solution to manage thepedestrian volume. For example, when the pedestrian volume in a certainplace exceeds a threshold of pedestrian volume, the flow management andcontrol strategy may include a measure such as limiting pedestrianvolume in the place, diverting pedestrian volume to a relevant place,increasing management and control personnel and resources, etc. When thepedestrian volume in a certain place is less than a threshold ofpedestrian volume, the flow management and control strategy may includea measure such as fully opening the place, reducing management andcontrol personnel and resources, etc.

In some embodiments, the flow management and control strategy may bedetermined based on a preset threshold of pedestrian volume. Forexample, when a sum of the current pedestrian volume and the count ofusers who query is greater than the preset threshold of pedestrianvolume, the flow management and control strategy may include a measuresuch as flow limiting and flow diverting, etc. When a sum of the currentpedestrian volume and the count of users who query is less than thepreset threshold of pedestrian volume, the flow management and controlstrategy may include a measure such as opening, etc.

In some embodiments, it may be determined whether to divert the flow toother places based on edge weights of edges between places correspondingto other nodes and the intended place in the sub-map. For example, whenthere is no relevant place in the target sub-map corresponding to theintended place, no flow diverting may be performed. When there is atleast one relevant place in the target sub-map corresponding to theintended place, the pedestrian volume may be diverted to the relevantplace. The way to diverting the pedestrian volume may be that thepedestrian volume is diverted to a plurality of relevant places at thesame time, or is preferentially diverted to a relevance placecorresponding to a node connected by an edge with a low edge weight. Theway to diverting the pedestrian volume may be to send recommendationinformation of the place corresponding to the node whose edge weightbetween the other node and the intended place is smaller than a presetthreshold to a user terminal corresponding to a user who initiates aquery.

Through the above process of diverting the pedestrian volume, localmanagement and control of the pedestrian volume can be realized, and onthe premise of meeting the requests of users, unnecessary dangers causedby the accumulation of pedestrian volume can be avoided.

In some embodiments, the method for counting and regulating pedestrianvolume in a public place may further include determining whether tocontrol the flow of the intended place currently based on predicted flowof the intended place at a future time. For example, when the predictedflow at the future time is greater than a preset threshold, the flowcontrol may be performed on the intended place.

The flow at the future time may be the pedestrian volume in the intendedplace at a future time. In some embodiments, the flow at the future timemay be determined based on popularity of intended place. For detaileddescription regarding the flow management and control for the intendedplace at a future time, please refer to the determination andimplementation of the above-mentioned flow management and controlstrategy.

In some embodiments, the object platform may determine the popularity ofthe intended place based on the count of users who query the intendedplace.

The popularity may be a preference of the user for the intended place.The popularity may be determined in a plurality of ways. For example,the popularity may be determined based on a count of the place that isregarded as an intended place in the query requests of users. Thepopularity may be determined based on user reviews of the place, such asa count of online positive reviews. The popularity may be determinedbased on real-time pedestrian volume information, or the like. In someembodiments, the popularity may be represented by a specific value, forexample, the popularity may be a value from 1 to 5, the larger the valueis, the more popular the intended place may be.

In some embodiments, the object platform may adjust the currentreal-time flow of the intended place based on popularity to determine aflow at the future time.

The flow at the future time may be calculated through the followingequation (4):

L _(w) =L _(D) +kH  (4),

where L_(w) denotes flow at the future time, L_(D) denotes currentreal-time flow, k denotes a constant (which may be any value from 60% to100%), and H denotes a value of popularity.

In some embodiments, an adjustment factor may be determined based on aconfidence level of the recommendation model, and the flow at the futuretime may be adjusted through the adjustment factor to obtain theadjusted flow at the future time.

The recommendation model may also include a confidence level. Theconfidence level may be a parameter reflecting the confidence degree ofa recommendation index output by the recommendation model. In someembodiments, the confidence level may be represented as a percentagefrom 0 to 100%. The higher the confidence level is, the higher theconfidence degree of the recommendation index output by therecommendation model is.

The adjustment factor may be a parameter for correcting flow at a futuretime. In some embodiments, the adjustment factor may be calculatedthrough the following equation (5):

$\begin{matrix}{{y = {\left( \frac{n}{10} \right) \times Z \times 100\%}},} & (5)\end{matrix}$

where y denotes an adjustment factor, n denotes a recommendation indexoutput by a recommendation model, and Z denotes a confidence level ofthe recommendation model.

The adjusted flow at the future time may be obtained through thefollowing equation (6):

L=L _(w) ×y  (6),

where L denotes the adjusted flow at the future time. By correcting theflow at the future time through the adjustment factor, a predictionresult that is more in line with the actual situation may be obtained.

The flow management and control strategy of the intended place may bedetermined by the method described in some embodiments of the presentdisclosure. The flow management and control strategy may be adjustedaccording to the change of the pedestrian volume, so as to meet thereal-time management and control requirements of the dynamic change ofthe pedestrian volume. In addition, the future pedestrian volume may bepredicted through popularity, so that future management and control canbe planned in advance to improve current and future travel experience ofusers.
